Used to be perfect

Wish I never rated this. It used to be ad free and big and easy on the eyes to use. Today, after YEARS of use, it asked me to rate it. I gave it 5 stars.

Then I went back to use it and cannot believe how it changed in less than a minute. It no longer fills the screen and it has advertisements and watch the video theme selections and menu options that take up real estate where before it was a simple and functional calculator.

I am dismayed and Apple and Apps. They used to provide endless fun or utilitarian functional. I paid a price and I could use my purchase much like software on my computer. Now, it seems like every app, even a simple calculator has turned into a money making gimmick.

I am about to return to a simple functional phone and buy a hand held gaming device for ad free entertainment. The old apps I have enjoyed are not being supported in future Apple upgrades and the new ones require more than I am willing to give to continue using them.

It's awesome but..

I really like the app itself it's perfect for hiding pictures and screenshots!
It looks just like a calculator and works like on too! You just time in a password add a % and it opens up!
BUT.. after loading 15 picture it wants you to pay $4 to add more. And when you open the calculator after password it's has these pop up ads that take forever to get rid of becfore you can see your pictures! Sometimes I would need to see a screen shot quickly and it would take forever just to the ad to go away!!! ANNOYING! There are other app just like this that don't do that! So just keep looking!

Love Calc & widget

On iPad mini 2 this app does it all. Yes there are ads, but they pay for a great app. It shows a running tape directly beneath the total, and has what I need to grade the student tests. Plus, I can do it all from the widget and if I tap on the widget to open it in the app, all of what I already typed is there, too. I don't have to start over.
You can unlock new skins by watching ads, or paying less than a dollar if you need a different skin/color scheme.
